GEORGE HAYES, OF NEV YORK, N. Y.

WINDOWfSLAT ADJUSTER.

` SPECIFICATION forming part of Letters Patent No. 279,156, dated June12, 1883.

Application filed April 3, 1882. (No model.)

To all whom it may concern;

Be it known that I, GEORGE HAYEs, a resident of the `city, county, andState of New York, have invented a new and useful Device for Opening,Closing, and Self-Locking (in either position) Louvers, Slats, orValves, of which the following is a specification.

rIhe object of my invention is the opening of a series of slats, valves,or louvers simultaneously, and when opened holding them se curely lockedin that position, and by reversing the device closing them, and whenclosed holding them securely locked in that position; and my inventionconsists in a device comprising a rod or sliding bar provided with asupporting-bracket at or near its upper end and anothersupporting-bracket at or near its lower end, the latter being providedwith a spring arranged and adapted to engage with the sliding bar, sothat by its pressure the bar will be held and kept from sliding,(without Vapplication of exterior aid.) The bar runs connect it witheach through grooves in each bracket; or it may be provided with a slotthrough itself, a pin being passed through the slot therein to steadyit. The spring may be attached to the bar and engage with the bracket,or it may be attached to the bracket, so as to engage with the bar, theone way being equivalent to the other. Spurs or links extending from thesliding rod slat, valve, or louver by hinged or pivot joints, and theentire combination of elements is such that when the rod is drawn up thevalves or louvers are shut and locked, and when the rod is drawn downthe valvesor louvers are opened and locked in that position.

In the accompanying drawings, Figure l is an elevation showing insideface of louvers or valves with my device in position. Fig. 2 is aperspective view of the same'. Fig. 3 is a sectional view, showing theposition of the device when the louvers are closed,'and by dotted linesshowing the position of device and louvers when open, also the spring onthe bracket. Fig. 4 shows an equivalent arrangement, the spring being onthe rod. Fig.

Vthe rod with the louvers, Ste.,

5 shows another equivalent arrangement, in which the rod itself isnotched.

A represents the walls of the structure, which may be of a building,clear story, tower, or turret.

B is the lower bracket, and C is the upper bracket, to either of whichthe spring for holding the rod may be applied.

D is the rod or sliding bar, of anysuitable sectional form, and it mayrun in slots or grooves ofthe brackets, or, by means of a slot initself, straddle'one or both brackets.

E, at the lower end, is a ring or hook, af-A fording a place forconnecting a cord thereto, and the one corresponding at the top answersthe same purpose, so that it may be drawn upward and downward by cords;or it may be raised and lowered by hand, or by pole and hook, as desiredand most suitable, according to the location.

F represents the spurs or links connecting one 'to each louver.

G represents the louvers, slats, or valves.

H represents the spring, the operation of which (by its pressure) servesto keep the rod or bar, when drawn up, from falling. This spring may bedispensed with when cords or chains are used to operate the rod, as thecords, Src., might be at that time fastened to some suitable place; butthe spring is essential when no cords are used. This spring H may beattached to either bracket and press the rod, or vice versa. A nick orsocket is made therein, at I, to t snugly over a projection, J. The formand location of the parts I and J, however, may be varied to suitcircumstances.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

In combination with slats, valves, or louvers G, the rod D, providedwith supporting-brackets B and C, and links F, substantially as shownand described.

GEORGE HAYES.
